Pinch control2: laser drawing

[atduskgreg] posted this cool looking rig. That’s a batting glove, chopped up and equipped with a flex sensor and a pressure sensor. The end goal was to create a new method of drawing. You can see he’s interfaced with the servos decently. It seems fairly responsive and intuitive. Looking at his results though, make us wonder if all that effort was worth it. We would probably apply this rig to some kind of animatronics.

To draw on a wall with a laser you need a closed-loop galvo scanner, everything else is too slow or too unprecise. Two servos, that’s way too unprecise even to draw with a pen, let alone with a beam on a wall.
